During process shutdown, it was possible that an `ImageBitmap` was created that would later be used after being freed from a different codepath, leading to a potentially exploitable crash. This vulnerability affects Firefox < 118.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - During process shutdown, it was possible that an `ImageBitmap` was created that would later be used after     being freed from a different codepath, leading to a potentially exploitable crash. This vulnerability     affects Firefox < 118. (CVE-2023-5175)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202401-10 (Mozilla Firefox: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox. Please review the CVE identifiers     referenced below for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-a0ac4fe21c advisory.

    - Updated to latest upstream (118.0)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6404-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2023-5169, CVE-2023-5170,     CVE-2023-5171, CVE-2023-5172, CVE-2023-5175, CVE-2023-5176)

    Ronald Crane discovered that Firefox did not properly manage memory when non-HTTPS Alternate Services     (network.http.altsvc.oe) is enabled. An attacker could potentially exploit this issue to cause a denial of     service. (CVE-2023-5173)

    Clment Lecigne discovered that Firefox did not properly manage memory when handling VP8 media stream. An     attacker-controlled VP8 media stream could lead to a heap buffer overflow in the content process,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-5217)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-7a4026e363 advisory.

    - Updated to latest upstream (118.0)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-587dc80bb1 advisory.

    - Updated to latest upstream (118.0)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 118.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-41 advisory.

  - A compromised content process could have provided malicious data to <code>FilterNodeD2D1</code> resulting     in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
    (CVE-2023-5168)

  - A compromised content process could have provided malicious data in a <code>PathRecording</code> resulting     in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
    (CVE-2023-5169)

  - In canvas rendering, a compromised content process could have caused a surface to change unexpectedly,     leading to a memory leak of a privileged process. This memory leak could be used to effect a sandbox     escape if the correct data was leaked. (CVE-2023-5170)

  - During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing     an attacker to write two NUL bytes, and cause a potentially exploitable crash. (CVE-2023-5171)

  - A hashtable  in the Ion Engine could have been mutated while there was a live interior reference, leading     to a potential use-after-free and exploitable crash. (CVE-2023-5172)

  - In a non-standard configuration of Firefox, an integer overflow could have occurred based on network     traffic (possibly under influence of a local unprivileged webpage), leading to an out-of-bounds write to     privileged process memory.  This bug only affects Firefox if a non-standard preference allowing non-HTTPS     Alternate Services (<code>network.http.altsvc.oe</code>) is enabled. (CVE-2023-5173)

  - If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently     freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. This bug only     affects Firefox on Windows when run in non-standard configurations (such as using <code>runas</code>).
    Other operating systems are unaffected. (CVE-2023-5174)

  - During process shutdown, it was possible that an <code>ImageBitmap</code> was created that would later be     used after being freed from a different codepath, leading to a potentially exploitable crash.
    (CVE-2023-5175)

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. Some of these bugs     showed evidence of memory corruption and we presume that with enough effort some of these could have been     exploited to run arbitrary code. (CVE-2023-5176)
